Our DD is the same age We're giving her a trike with a detachable handle for us to push, a doll & books. She already has loads of arty crafty stuff, and she loves it all.

She also LOVES her tea-set (makes us "hot tea" all the time and really pours the pot nicely etc). Other thing she plays with a lot is a simple little wooden bed for her dolls that DH made out of some off-cuts. I sewed up a "doona" for it, and she is always putting all her toys to bed in it. She even put all her plastic animals in it, one by one. They are much loved too, just a bag of farm animals I got from a garage sale - best $2 ever spent!
